6904.90.00.00 - Other

This HTS category, 6904.90.00.00, encompasses ceramic articles primarily intended for building and construction purposes, excluding those specifically classified as building bricks. It broadly covers a variety of ceramic products utilized in the construction industry, such as flooring blocks, support tiles, filler tiles, and similar items, which do not meet the precise definition of a "building brick" as per heading 6904.10.00.

The distinction between this residual category and its sibling, 6904.10.00, lies in the specific form and intended use. While 6904.10.00 is dedicated to ceramic articles that function as structural components in walls or similar constructions, this category captures other ceramic building elements. For instance, flooring blocks are designed for pavement or floor construction, and support or filler tiles are used to create voids or structural elements within larger assemblies, rather than as primary load-bearing walls.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification within 6904.90.00.00 relies on carefully assessing the physical characteristics, dimensions, intended application, and material composition of ceramic articles to ensure they are not specifically enumerated under other headings within Chapter 69, nor the distinct category of building bricks. Examples could include unglazed quarry tiles, certain types of decorative ceramic floor tiles used in architectural applications, or modular ceramic elements designed for specific building systems.
